MATTHEW S.

WALKER, OF CORNNG, NEW YORK.

ELECTRIC-LIGHT FIXTURE. c

Specication of Letters Patent.

Patented July 2% 1919.

Application filed October 24, 1918. Serial No. 259,48?.

To all whom it may concern:

Be it known that I, MA'rrHEW S. WALKER, a' citizen of the United States, residing at Corning, in the county of Steuben and State of New York, have invented certain new and useful Improvements in Electric-Light Fixof which the following is a specication.

lThe invention. provides hat might be termed a deskvlamp since it 's portable and designed'most especially for use on desks, tables, and analogous articles of furniture.

The invention has for its object to provide lan electric lampwhich will protect the globe,

serve as a shade to' restrict the raysof light,

.-act as a -reflector to shed the light rays in the required direction and which is ornamental and susceptible to be secured to the edge of a desk or other supporting means.

The drawing illustrates a. preferred embodiment of the invention, however, it is to be understood that in adapting the same to meet dierent conditions, various changes in the form, proportion, and minor details of construction ma parting from tli as claimed hereinafter.

Referring to the accompanying drawings,

Figure l is a view in elevation of an electric lamp embodying the invention.

Fig. 2 is a vertical central section, the dotted lines indicating the manner of securing the lamp to the edge of a desk, table 'or the like.

Fig. 3 is a view in elevation showing several adjustments by `lull and dotted lines.

Fi f. 4 is a sectional view showing more clear y the clamp arm.

' Corresponding and like parts are referred to in the following description and indicated the drawing by like reference characters.

The lamp comprises a stand and a cover, the latter acting as a shade and a reflector. rihe lamp is indicated at 1, and consists otx the usual bulb containing a filament and adapted to make connection with asocket 2. A conducting wire 8 is attached to the -socket 2 in a manner well understood `and is provided 'with a plug t to make connection with a snitableterminal, such as provided for plugging in electric devices ot a portable character.

The stand comprises a base 5, a top S and an intermediate connecting portion TI, The

be resorted to without dee nature of the invention" at its opposite end to vot licht in ail f rc nircd direction.

top S and' base 5 are flared and the latter receives a weighted ring fxwhich ser` es t0 give stability'to 'the fixture and also to renforce the base and prdvide for attachment to the stand of a clamp 9 which is hinged to the ring 8 and comprises stepped portions. A contractile helical spring 1G attached at one end to the clamp 9 is made secure at its opposite end to an anchoring elementll whiclrpreferably consists of a disk located in the lower contracted portion ot' the top 6. The terminal portion 12 of the clamp 9 constitutes a finger piece and a stop. The intermediate portion 13 constiu tutes the jaw or gripping element of the clamp, whereas the part 14 acts as a stop to limit the movement of the clamp when engaging a desk or other projecting part to which the lamp is to lie-attached.

The cover 15 is of flared form and is pro-- vided-at its lower edge with a rim 16 to embrace a complemental rim 17 at the u per end of the stand. The upper portion o the cover is formed with a neck 18 which receives the lower portion of the socket and which is adapted to be engaged by a clamp 19 at one end of an arm 20 which is pivoted the upper end of an adjustable standard. Thebulge of the globe 1 engages the lower end of the neck 18,'

whereas a shoulder of the socket' 2 engages l the upper end of the neck 18 said neckbeing clamped between the globe and' socket, whereby sil h partskare retained in the required position. The cover Al5 acts as a shade and its inner wall is nished so as to act as a reflector to throw the rays of light in the required position.

The adjustable standard located at one side of the xture and comprises

members

21 and 22 which have a telescopic arrangement to admit of the cover 15 being raised or lowered. The member 21 is rotatable in the member 22 thereby admitting ofthe cover being swung horizontally to any angu` lar position. The member 2 tubular and its lower end is secured to an extension of the base 5 Whereas a brace 23 secures the upper portion of the member Q2 to the top 6 of tbc stand. It fastening Qfipivotally connects the arm 2O with thc upper end of the member 21 and by setting!I the arm 20 the cover 'l5 may bc adjusted to throw thc rays r1`his is indicated by thc full and dotted lines in Fig.

` Which is fitted a thumb nut.

When the lamp is not required for use the cover 15 is closed upon the stand, thereby protecting the globe 1. Vhen the lamp is required for use the cover is raised and moved to any required adjusted position so as to direct the rays of light to best suit the Wants of the user. Tliemember 21 is adapted to be held frictionally to the member 22 in the required adjusted position and this is eected by a binding action due to the fact that the weight is to one side of the member 21. However, any suitable means may/'be employed for holding the member 21 in the required position such as commonly provided in adjustable standards of book rests and analogous article supporting means.

The foregoing description and the dra-W- ings have reference to what maybe considered the preferred, or approved, form o-f my invention. It is to be understood that I may make such changes in construction and arrangement and combination of parts, materials, dimensions, et cetera, as may prove expedient and fall Within the scope of the appended claims.

Having thus fully described my invention, What 1 claim as new and desire to secure by Letters Patent is 1. In an electric light fixture, a stand comprising a base, a top and an intermediate hollow connecting portion, a Weighted ring in the base, a clamp disposed Wholly Within the base and connected at one end to the Weighted ring and stepped in its length to provide a finger piece, a grip and a stop, a disk located in the lower portion of the top, and a contractile helical spring disposed in the hollow connection between the top and base and attached at its ends to the said disk and clamp, respectively.

2. In an electric light fixture, a stand comprising a flaring top, a flaring base and a relatively small connecting portion, a cover for the stand formihg a shade and a reiector and having a neck portion, an arm engaging the neck portion of the cover, a fiXed member secured to the base and top of the stand, and an adjustable member mounted in the fixed member to slide and turn therein and having the said arm pivoted thereto.

In testimony whereof 1 affix my signature in presence of two Witnesses. n
